(n., from Japanese ガンギマリ, also ガンギマリ顔 “gangimari face”)
The state of drug-crazed euphoria when you're
high as a kite, usually from marijuana,
methamphetamine, or asacoco.
Etymology: Portmanteau of ガンジャ “ganja” (marijuana) and キマり キマっている “kimari/kimatteiru” (slang for the euphoric effects after drug consumption, original meaning “to look good in”), also
onomatopoeic ガン “gan” like a gong being hit
